@TomBurgmann: Unfortunately my wife has other more pressing projects to while away my hours.

It's sad to see a good man brought down so low in this way LOL

"Progress isn't made by early risers. It's made by lazy men trying to find easier ways to do something."― Robert A. Heinlein


I have to admit that your Eager Beaver ways of building these NxNxN cubes appeals to the engineer nerd in me - BUT - I try to remember the RAH quote above and think it through before I start building.  If I had Protean Pete to help I might launch into the same project. Unfortunately my wife has other more pressing projects to while away my hours.

I will leave you with this thought. Prove a^n + b^n = c^n, solve for n>2.

Meanwhile I'll ponder my elegant solution and publish it before I retire. If there had been more room in this post I could have scribbled it down here ;-)

@kevinwongs: Very cool idea. With so many solder points. how to you plan to solder those. With any of these soldering irons it will take a lot of time... 

By my calculation and when the cube finally rests on its PCB there will have been 2384 solder joints made. I use a fairly cheap solder station like this one.

I'm building the cube in 8 flat 8x8 panels. The blog for the construction of these panels will be posted in the next few days, here is a link to the video in the meantime. The 8 panels will then be assembled into the cube. It has taken me a couple of months doing a bit as and when time allows to get this far.

@Mike Field: Imagine a set of 512 of these: http://www.adafruit.com/products/1734 coupled with 

http://hamsterworks.co.nz/mediawiki/index.php/Intelligent_LEDs

You could drive your whole LED cube in 24 bit colour, with a 30Hz refresh rate, using one pin of a FPGA. Each LED buffers the signal, tidies it up and hands it off to the next LED.

All you need is a 5V @ 30A as each LED is 0.3W,

What can I say, if only the Neo-Pixels were available before I started this project. I am where I am and it's to late to change. I already have experience with the Neo-Pixel strips as well so quite used to coding them. Maybe the next cube.

Max has bought enough Neo-Pixels and intends on building an 8x8x8 cube with them. Lets see how he gets on. I was looking to see if I could adapt my PCB design for him to use.

You could free-wire it like https://learn.adafruit.com/free-wire-3x3x3-neopixel-cube

@alex: That will start that way, and next thing you know you'll adopt a german accent and plan to take over the world?

Vot? LOL
